How do you detach bucket from inside the cab of excavator?
Flip the toggle switch, the alarm will sound and wait for the wedge bar to move out or one some you have to use a function like bucket curl in to build the pressure to move the wedge bar and then unhook the bucket from the machine
It would help to know what model of excavator, what year, what style coupler.. etc.
